I am  looking for european supplier for "mechanical etching" bits for
using with  home-made CNC router. Any suggestions?



Surely you use solid-carbide PCB-drill-bits?  When they break, SAVE  the 
shanks, and GRIND an "etching bit" on the tip!  (use a diamond-grit  wheel).   
 If you can home-brew a CNC router, you can SURELY  grind the tip of a 
carbide "blank"!
